To all 'z/lzoff/zy it may concern:

Be it ltnoivn that l, FREDERICKVnRrLAsr, of Boston, county of Suffolk, State of lilassachusetts7 have invented an improvement in Automatic l'lileighing-laiachines, ot ivl ich the. following is a specilication.

rllhis invention relates to automatic Weighing machines of the platform variety, and has i'ior its object to provide the machine with a display-case by which articles t merchandise ot various kinds may be displayed, said case being arranged to torni component part et the structure constituting` the frameavorlr or case ot the machine; and to provide t'or the free and unobstructed movement ot' the platform-rod Which extends up through the display-case and which is connected -with the indicating device which located above said case; also to provide the machine base with an extension which supports the display-case and to provide said extension With a top plate which is adapted to serve as the bottom plate ot the display-case and to provide the top plate ot the extension and the top plate ot the display-oase7 each With a hole through it ttor the platform-rod; also to provide means tor securely holding the top plate of the displaycase in fixed position With relation to the machine oase; also to provide an upright tube, ivhich, tor its platform rod and to provide said tube, at its opposite ends. 'With means tor engaging the top plate ot the extension and with means for engaging the top plate et the display case to thereby hold said 'plates in tixed relative positions; also to provide an upright tube which incloses the platform-a rod tor its entire length, and vfhich is rigidly connected at its lovfer end to the top plate ot the extension ot the machine-base and tvhich extends up through the hole in the top plate oie the display-case and therel y holds said top plate in lixed position relative to the top plate ot the extension.

Figure l shoivs in trontelevation a weighing-machine embodying this invention. Fig. 2 is a vertical section ot the machine taken on the dotted line 2 Fig. l. Fig. 3 is a horizontal section ot' the machine, taken on the dotted line 3 3 Fig. 2. Fig. il is a horizontal sect-ion ot the machine, taken on the dotted line 4 4 Fig. 2.

c. represents the machine-base, b the platform, c the balancing levers supporting the platform, (Z the upright vertically movable entire length, incloses the platform-rod, and c the indicating-niechanism of an automatic Weighing machine ot any usual or suitable construction.

lhe machine-base o is formed or provided With an extension o or any suitable shape and size t'or supporting the display-case, and said extension has a top plate b3, formed integral with it or it may be otherwise rigidly connected With it, ivhich serves as the bottom )late ot the. display case. rrs it is desired to provide a display case of quite large dimensions said extension Z2 is herein shoivn as ext-ended laterally in 0pposite ivays 'trom the main portion ot the machine-base and also rearwardly theretrom. For the purpose ot illustrating my invention the display-case herein shown consists oil an upright structure supported on the extension 7) ot the machine-base and made quadrangular, its tour side Walls being secured together at thc corners by clips j" or otlnrwise. The lower ends or the sido ivalls enter a recess which is termed in the top ot the extension o ot the machine-base, so thatl the display case rests upon the top plate lf. This recess is formed at `the top et the extension o by providing said extension ivith an upwardly extended tlange be which surrounds the top plate 3. The flange holds the loiver ends ot the side plates against lateral displacement. rlhe upper c d of' the case is closed by a plate f2, pret'- erably ot glas., .ivhich rests on top ot' the side Walls This top plate is ot considerable thichness in order that it may be used partially or Wholly to support the head g which inclcses the indicating-mechanisnr The top plate ot the extension ot the machine-base and the top plate 7"2 ot the display-case are each formed with a hole it tor the platform-rod al, said holes g arranged in vertical alinement. i tube /1 extends from top to bottoni ot the disnlav-caso. which is preferably centrally disposed. lt is rigidly conne-c 'ed at its loivcr end to the top plate 7%* ot the extension of the machinebase. and rigidly supports against lateral movement the top plate ot the display-case. that is to say7 it holds the top plate ot the display case in lixed position relative to the top plate of the extension. lts loiver end extends into and preferably through a hole in the top plate b3 of the extension of the machine-base and is rigidly connected with said plate by screiv'ing it into said hole7 hence the scren7 threads serve llt) as a means on the tube for engaging the top plate of the extension. lts upper end eX- tends up through the hole in the top plate f2 of the display-case, and means connected with its upper end portion are employed for securely holding said top plate in fixed position. Said tube, for its entire length, incloses the platform-rod, and thereby protects it so that it has a free and unobstructed movement. As said tube is rigidly connected at its lower end to the top plate of the eX- tension and is provided with means for engaging the top plate of the display-case, it serves to rigidly connect the top plate of the display-case with the machine-base and to thereby support it against lateral movement. By rigidly supporting the top plate of the display-case against lateral movement any strain exerted thereon incident to moving the machine from place to place will not act to strain and thereby crack the glass side walls.

lt will be observed that the top plate b3 on the extension of the machine base and tube It rigidly connected thereto serve as and constitute an upright supporting-frame for the top-plate and side walls of the display case, which is connected with and supported by the extension of the machine base, and that said upright supporting-frame has a passage through it for the platform-rod, but my invention is not limited to the employmentof this particular form of uprightsupporting-frame for display case. It is very important to protect the platform-rod in order that it may have a free and unobstructed movement, for the reason that if movement of this rod is in the least obstructed the machine will not weigh accurately.

The platform-rod which extends through the tube from end to end is connected at its upper end in any usual manner, not shown, with the usual indicating-mechanisni. rlhc head g which contains the indicating-mechanism is made hollow and has in its front side a circular opening for the dial. lt is attached at its lower end to a plate gf resting on the top plate fgof the display case. The plate g" has a hole through it for the projecting end of the tube t. fr disk f/Z having an internally screw threaded hole through it, is screwed onto the externally screw-threaded end of the tube .7L and engages the plate g and acts to clamp said plate g between itself and the plate rfhe head g is thereby securely held in place, and the top plate f2 is held in engagement with the upper end of the tube it and by means of said tube is held in fixed position.

Gn the tube It at diderent points within the case, collars it are secured, preferably adjustably, by means of set-screws h2 or otherwise. Arms its of any desirable length, extend outward in different directions from 'desired to display, but my invention corn-- 75 these collars. The arms on each collar occupy a horizontal plane to thereby adapt them to support shelves z', which may be made of glass and which may merely rest on said arms. The shelves, any desired number of which may be employed, may be made of any shape or size. They are particularly well adapted to receive upon them diiferent articles of merchandise which it is prehends the employment of any other form of Cisplaying-devices contained in the display case for supporting the articles of merchandise for the purpose of displaying' them, in lieu of the shelves herein shown.

One wall of the display case will be made as or provided with a door, represented at f3, Fie'. 2. By making all of the walls of the display case of glass the articles of merchandise may be seen by bystanders from all sides of the machine, yet by making merely the front wall of glass the articles may be seen by a person standing on the platform. Hence l prefer to malte the display case practically entirely of glass. By making the tcp plate of glass a person standing on the platform may lool down through it and see the articles from a different view point, but as the primary object of this Vplate is to assist in supporting the head which contains the indicating-mechanism it need not be made of glass.

Having thus described my invention, what l claim as new and desire to secure by Letters l atent is z- 1.
